GILLING MACHINE AND DRAWING MACHINE FOR THE TREATMENT OF FIBROUS MATERIALS Original Filed July 28, 1954 Patented Mar. 2, 1937 UNITED STATES PATENT OFFICE GILLING MACHINE AND DRAWING MACHINE FOR THE TREATMENT OF FIBROUS MA- TERIALS John Hughes, Rochdale, England This invention relates to improvements in gilling machines, worsted draw frames and like machines for preparing fibrous material for spinning or other treatment or use, as described in the specification of the co-pending application for Letters Patent Serial No. 737,367 filed July 28, 1934, of which the present application is a division.

The invention provides a hand lever or the like by movement of which in one direction or the opposite direction into one or other of two positions a top roller ordinarily subject to pressure applied at or near its ends by means of a spring or springs or a weight or weights in a pair or set of back rollers in an intersecting gill box comprising upper and lower sets of fallers, or in a gill box with a single set of fallers, or in a worsted draw frame or analogous machine, may be allowed to bear on the bottom roller or rollers or on fibrous material between said top roller and the bottom roller or rollers, or may be relieved of the pressure ordinarily applied. In a preferred construction the top roller is arranged to be raised clear of the bottom roller or rollers by the movement of the hand lever so as not to bear on the bottom roller or rollers, and is, preferably, adapted to be set free for convenient removal from the machine.

In the accompanying drawing, in which parts already in use and in public knowledge are shown only in part but sufiiciently to show the application of parts provided according to the invention, Fig. 1 is a front elevation, broken to shorten the figure, showing a top and bottom roller and other parts of -a gill box, worsted draw frame or analogous machine, and parts for raising the top roller and releasing it for removal from the machine. Fig. 2 is a plan, broken to shorten the figure, of the parts shown in Fig. 1.

Fig. 3 is a side elevation, showing a shaft in vertical section on the plane indicated by the line III-III of Figs. 1 and 2. Fig. 4 is a side elevation, generally similar to Fig. 3, showing the same parts with some moved into different positions.

The same characters of reference indicate corresponding parts in the several views.

Referring to the drawing, 43 denotes a lever or frame, for clearness and simplicity herein termed the relieving lever or frame, which, forming a hand lever or being connected to a hand lever and being movable about a center-line between limits determined by stops 44, 45 provided on stationary parts 46, 41, is formed with a stop 43* and is also provided with arms 48, 49 extending beneath end journals 50, 5| of the top roller 52 6 Claims. (01. 19-135) so as to be capable of lifting said roller 52 on movement of the hand lever 43 in one direction. The stationary parts 46, 41 are formed as extensions of bearing caps serving to hold in the parts 53, 54 of the framework of the machine the journals 55, 56 of the lower roller 51. The 5 stop 44 is formed by the exterior of the bearing cap of the journal 55. Studs 58, 59 in the parts 46, 41 form pivots for the relieving lever or frame 43. Loading levers 55, 6! for applying pressure to the top roller 52 at or near its ends are under the influence of springs 62, 63 so applied-as, according to the position of the levers 60, 5| at any time, to act in a plane on one side of the pivotal axis of said levers 66, 6| and thus to apply pressure on the top roller 52, or in a plane on the other side of said axis and thus to apply no pressure on the top roller 52. The levers 60, BI are mounted to oscillate about the studs 58, 59 and are respectively formed with arms 64, 65 with concaves in the lower faces thereof to bear on the journals 5!], 5i and are also respectively formed with orificed ears 66, 61 movable from one side to the other side of the pivotal axis of the levers 66, 6|. The springs 62, 63 are applied around rods 68, 69 hooked at their upper ends in the ears 66, 61 of the levers 60, 61 and screw threaded at their lower ends for engagement by adjustable wing-nuts 10, ll whereby the springs 62, 63 may be compressed between washers 12, 13 bearing against the nuts 10, H and centering and bearing blocks I4, 15 with bearing fulcra l6, l! to bear against projections l8, 19 formed on the parts 53, 54. The relieving lever or frame 43 is provided with striking or engaging parts 80, 8| for acting against the levers 60, 6| and moving them off the top roller 52 whereby the line of action of each spring 62, 63 is transferred from one side to the other side of the pivotal axis of the levers 60, 6| on movement of the lever or frame 43 in one direction, and also with other striking or engaging parts 82, 83 which in the movement of the lever or frame 43 in the opposite direction act upon the levers 66, 6| to cause the line of action of each spring 62, 63 to be shifted in the other direction past the pivotal axis of the levers 60, 6|, which are thereby caused to bear on the top roller 52; said parts 82, 83 also acting as stops to limit movement of the levers 60, 6! away from the top roller 52. The lever or 50 frame 43 is preferably so formed, as illustrated, that the movement of the levers 60, 6| off the top roller 52 begins before the top roller 52 begins to be lifted. In the preferred construction illustrated the striking or engaging parts 82, 83 are crum, whereby, depending on the position of said..-

lever, to cause pressure to be applied or not to be applied through said lever to said top roller, a manually operable member mounted to rock on a fixed axis and having at least one part extending beneath said top roller whereby to lift said top roller when said member is rocked in one direction, means on said member engageable with said lever when said member is rocked in said direction to lift said lever from said top roller,

striking means on said member engageable with said lever when said member is rocked in the opposite direction to cause said lever to bear on said top roller, and stop means limiting the movement of said member.

2. A gilling machine orlike machine embodying the combination recited in claim 1 in which the manually operable member when rocked in one direction lifts the lever off the top roller before beginning to lift the top roller.

3. A gilling machine or like machine embodying the combination recited in claim 1 in which the striking means on the manually operable member affords a support for the lever when the lever is lifted from the top roller.

- roller, a manually operable structure mounted to rock on a fixed axis and having parts extending beneath said top roller whereby to lift said top roller when said structure is rocked in one direction, means on said structure engageable with said levers when said structure is rocked in said direction to lift said levers from said top roller, means on said structure engageable with said levers when said structure is rocked in the opposite direction to cause said levers to bear on said top roller, and stop means limiting the rocking movement of said structure in the direction to lift said top roller.

5. In a gilling machine or like machine, in combination with top and bottom rollers, a pair of levers having a common pivotal axis and each adapted to bear on the top roller adjacent to the ends of said top roller, spring means acting on said levers on one or the other side of said axis, whereby, depending on the position of said levers, to cause pressure to be applied or not to be applied through said levers to said top roller, a frame provided with a handle and mounted to rock on a fixed axis and having arms extending beneath said top roller adjacent to the ends of said top roller, whereby to lift said top roller when said frame isrocked in one direction, means on said frame engageable with said levers when said frame is rocked in said direction to rock said levers away from said top roller into a position in which pressure is not applied to said top roller, and means on said frame engageable with said levers when said frame is rocked in the opposite direction to cause said levers to bear on said top roller.

6. In a gilling, or like, machine, in combination with top and .bottom rollers, at least one lever havinga fixed; fulcrum and adapted to bear on the topv roller, spring means acting on said lever onone side of said fulcrum, whereby, depending onthe position of said lever, to cause pressure to be applied on occasion through said lever to said toproller, armanually operable member mounted to rock on a fixed axis and having at least one part extending beneath saidtop roller whereby to liftsaid toproller when said member is rocked in one direction, means on said member engageable with said lever when said member is rocked in said direction to move said lever on its fulcrum away from said top roller whereby said spring means-is caused to act on saidopposite side of said fulcrum, striking means on said member engageable with said lever when said member is rocked in-the opposite direction to cause said lever to bear on said top roller, said last mentioned means presenting a rest for said lever when lifted clear of said top roller, and stop means limiting the, movement of said member.
